A VAFC is not made for tuning nitrous. Be warned. A 75 shot is high for a dry shot. As long as you use the AFC to add fuel you should be safe, but you'll be running that rich all the time, which is a waste. You'll need at least colder plugs, retard the timing a few degrees, and get a wideband to test your a/f to be safe.
Whats a wideband? thanks for everything
